IKEA Skadis Filament Swatch Holder

I made a little organizer for filament swatches I like to print with every new filament I buy. I came up with this solution, that can stand on its own or get hooked up on an IKEA Skadis board (I added some optional hooks you can glue or melt in the holes on the back of the holder). print laying on the back with -optional- some supports for the hook-holes. I made one version saying “Filament-Beispiele” and one that says “Filament-Samples”. The hook fits both (but you will need two). 

It was designed around this model of filament swatches:
